Passive and Active House Cooling 101


The summer heat is nothing to be trifled with.

The government just recommended that Americans sleep with the thermostat at 82 degrees.

This is a headline story for many reasons. One of the biggest because it’s an affront to our freedoms. It’s also wild because when the home hits 80 degrees the heat becomes noticeable and it can get pretty uncomfortable.

There are many ways humans have dealt with heat in places like the south for a long time. Before electricity, fans and air condition we had to stay cool and comfortable.

Let’s look at passive and active cooling techniques that can be used to cool your home in the summer.

Passive Cooling Techniques

The shade is one of the oldest methods of passive cooling. Whether we are talking about sitting under a shade tree or using trees to shade the home.

Reflective roofing and walls on a home are another great way passively cool your home. The heat along with the rays of the sun is reflected away from the home.

If you are lucky enough to build a home you can also position portions of your home in such a way that it does not take the full brunt of the sun each day.

There are other very interesting technologies that use things like cooling towers and earth tubes to passively heat the home.

Active Cooling Techniques

Ventilation is a tremendous method of active cooling that can be taken advantage of during the hot summer months.

Evaporative cooling is another method of active cooling that is used by many people even in the modern age.

The management of heat and cold in an off-grid situation is critical. While sleep is not one preps we spend our days thinking about, you need to sleep if you are going to be prepared to take on the challenges of the day.
